Illinois holds a great diversity of natural habitats and communities, from cypress swamps in the south, beech-maple forests in the east, tallgrass prairies in the central region, steep bluffs and palisades along the western rivers, bogs and wetlands in the northern counties, and numerous other unique natural communities in between. As a state, we are fortunate to have a great legacy of individuals and organizations that have devoted immense time and efforts toward the study, protection, and care of our natural resources. Please join us as we strive to uphold this legacy and share our appreciation of Illinois’ natural treasures with current and future generations.

There are currently seven chapters of the Illinois Native Plant Society. Chapters host programs, hold native plant sales, offer workshops, conduct field trips, and organize symposia.

Members are asked to affiliate with a chapter and can choose more than one or all. Check the individual chapter pages for details regarding their calendar of events.
